County officials are trying to put some distance between a proposed 273-acre industrial park and homes near the site, just west of Dania in unincorporated Broward County.

In a 6-5 vote last week, the county Planning and Zoning Board approved plans for the park with the stipulation that the developer, Alandco, create a 900,000-square-foot buffer zone along the Dania Cut-Off Canal. The County Commission will consider the board`s recommendation on Oct. 4.

Alandco`s $159 million industrial park will be the third or fourth largest of its kind in Broward County, said Mike Frey, senior vice president of marketing for the Broward County Economic Development Board. Alandco is a subsidiary of Florida Power & Light`s parent company, the FPL Group.

The park would be south of State Road 84, north of the canal and just west of Ravenswood Road. About 50 homes face the site from the south side of the canal.

``We are pleased that the Planning and Zoning Board has seen fit to ensure the quality of life in the residential area along the canal by insisting on the buffer zone,`` said Donna Simione, a resident who attended the board meeting.

The buffer zone would be 4,500 feet long and 200 feet wide.

Andy Siegel, one of the board member`s who approved the buffer, said it would prevent homeowners from having to look at the complex and help maintain their property values.

Board member Emmett Tigue voted against the buffer. The board`s recommendation does not specify if the buffer should be made up of trees, shrubbery or berms, McTigue said. Board members also did not know whether 200 feet was wide enough, he said.

``I think that the developer of the property ought to take into consideration the sensitivity of the canal adjacent to it,`` McTigue said. ``But I think to adopt a buffer is probably not the best way to handle that.``

Instead, Alandco should present a plan for making the park`s south end compatible with the adjacent residential area, McTigue said.

The park is scheduled for partial completion by 1992. It would include 660,000 square feet of office space, 2.6 million square feet of industrial buildings and 100,000 square feet of commercial property.

In its application for conceptual approval of the project, however, the company did not say where the offices and industrial facilities would be located. The lack of specifics disturbed McTigue and other board members.

``I think when you`re asked to approve a development order and a rezoning request it is helpful to know where the developer plans to site the retail/ commercial, the office and the industrial,`` McTigue said.
